Each year red-winged blackbirds stop in a certain region of Midland Province on their spring and fall migrations. In the fall, they eat a significant portion of the province’s sunflower crop. This year Midland farmers sought permits to set out small amounts of poisoned rice during the blackbirds’ spring stop in order to reduce the fall blackbird population. Some residents voiced concern that the rice could threaten certain species of rare migratory birds. Nevertheless, the wildlife agency approved the permits.

Which of the following, if true, most helps to justify the wildlife agency’s approval of the permits, given the concerns voiced by some residents?


(A) In the region where the red-winged blackbirds stop, they are the first birds to be present in the spring.

(B) The poison that farmers want to use does not kill birds but rather makes them incapable of producing viable eggs.

(C) Since rice is not raised in Midland Province, few species of birds native to the province normally eat rice.

(D) Without the permit, any farmers shown to have set out poison for the blackbirds would be heavily fined.

(E) The poison that farmers got approval to use has no taste or smell that would make it detectable by birds.

Each year red-winged blackbirds stop in a certain region of Midland Province on their spring and fall migrations. In the fall, they eat a significant portion of the province’s sunflower crop. This year Midland farmers sought permits to set out small amounts of poisoned rice during the blackbirds’ spring stop in order to reduce the fall blackbird population. Some residents voiced concern that the rice could threaten certain species of rare migratory birds. Nevertheless, the wildlife agency approved the permits.

Which of the following, if true, most helps to justify the wildlife agency’s approval of the permits, given the concerns voiced by some residents?

Premise 1: RWB birds, during their Spring and fall migrations, eat a significant portion of crop.
premise 2: Farmers sought permissions to place small amounts of poisoned rice during spring break.
Conclusion : WildLife agency gave permission despite the concerns that rice could threaten certain species of rare migratory birds


We need to explain why?

A. In the region where the red-winged blackbirds stop, they are the first birds to be present in the spring.
This option says, the RWB birds are the first set of birds to come so it is quite possible that other birds would not be targeted as RWB birds will eat the poisoned rice first-> This explains why Wild life have given the permission and hence correct

B. The poison that farmers want to use does not kill birds but rather makes them incapable of producing viable eggs.
How the poison acts is immaterial to the context as the context is not how to poison will affect the bird but which birds will get affected.

C. Since rice is not raised in Midland Province, few species of birds native to the province normally eat rice.
We are not talking about native birds, we are talking about "rare migratory birds" so this option is out of context.

D. Without the permit, any farmers shown to have set out poison for the blackbirds would be heavily fined.
This is immaterial and out of context

E. The poison that farmers got approval to use has no taste or smell that would make it detectable by birds.
This is immaterial and out of context

A) if they are the first birds to stop in the spring season, hence they are the fisrt to eat the poisoned rice and not the rare species.

I really can't get any answer choice that makes sense.

By POE:

A - Doesn't justify. Even if blackbirds are the first to stop, it doesn't mean they would eat up all the poisoned rice.

C - Talks about native birds. Concern is about rare migratory birds.

D - Irrelevant.

E - It makes no sense if the poison is not detectable.


I am left with B.

The assumption that needs to be taken for B to be correct is that the word 'Threaten' used in the passage implies killing of the birds. On assuming this to be true, one can say that because blackbirds would be incapable of producing eggs, their population in the fall would decrease.
Regarding the other species, this would also impact them but would not be 'threatening'.

Any other comments to solve out this?

I chose A.

Each year red-winged blackbirds stop in a certain region of Midland Province on their spring and fall migrations. In the fall, they eat a significant portion of the province’s sunflower crop. This year Midland farmers sought permits to set out small amounts of poisoned rice during the blackbirds’ spring stop in order to reduce the fall blackbird population. Some residents voiced concern that the rice could threaten certain species of rare migratory birds. Nevertheless, the wildlife agency approved the permits. Which of the following, if true, most helps to justify the wildlife agency’s approval of the permits, given the concerns voiced by some residents?

A. In the region where the red-winged blackbirds stop, they are the first birds to be present in the spring. (CORRECT -- IF RED-WINGED BLACKBIRDS ARE FIRST TO ARRIVE IN THE REGION, THE FARMERS CAN TIME THE USE OF POISONED RICE SO THAT IT CAN BE USED TO POISON THE RED-WINGED BLACKBIRDS ONLY. BEFORE OTHER MIGRATORY BIRDS ARRIVE, THE USE OF POSION RICE CAN STOP.)

B. The poison that farmers want to use does not kill birds but rather makes them incapable of producing viable eggs. (THIS WILL THREATEN THE SUSTAINABILITY OF OTHER MIGRATORY BIRDS)

C. Since rice is not raised in Midland Province, few species of birds native to the province normally eat rice. (THIS IMPLIES THAT THERE ARE STILL SOME SPEICIES --- EVEN THOUGH IT SAYS FEW --- THAT EAT THE RICE, THUS IT DOES NOT ELIMINATE THE RESIDENTS' CONCERNS OVER PROTECTING OTHER MIGARTORY BIRDS.)

D. Without the permit, any farmers shown to have set out poison for the blackbirds would be heavily fined. (DOES NOT ADDRESS THE RESIDENTS' CONCERNS OVER PROTECTING OTHER MIGARTORY BIRDS.)

E. The poison that farmers got approval to use has no taste or smell that would make it detectable by birds. (THIS WOULD RAISE THE RESIDENTS' CONCERNS EVEN MORE.)
